How is a galvanometer used to detect and measure current in a circuit?

Ans: A galvanometer is a device used to detect and measure electric current in a circuit. It operates based on the principle of electromagnetic induction, which means that when an electric current flows through a wire, it produces a magnetic field around it. The more current, the more the coil moves. This movement is measured on a scale to determine the current’s strength. It’s often used as the basis for ammeters to measure current in a circuit accurately.
